The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 2.4 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 2.8 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.5 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00049 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.59 SJR: 0.429 SNIP: 0.507 CiteScore™:: 3.9 H-Index: 49

SINOPSIS

According to our previous data, hematoporphyrin dimethyl ether (HPde) at concentrations useful for photodynamic therapy can radiosensitize aggressive Ehrlich ascite carcinoma (EAT) to 2Gy irradiation inducing total tumour growth inhibition. The aim of this study was to further investigate the possible mechanism of radiosensitization of EAT by dicarboxylic porphyrin-HPde. Our results reveal that HPde is inducing several rearrangements in the EAT cells: 1.2 × 10−6 M of the photosensitizer diminishes the number of cells in mitosis by a factor of 3, increases the number of cells in the S phase of the cell cycle, modifies the activities of antioxidant enzymes glutation S-transferase (GST) and DT-diaphorase (DTD), and eventually induces slight apoptosis. Moreover, it was shown that HPde is a ligand of peripheral benzodiazepine receptor (PBR). Named "house keeper," PBR is usually responsible for all these perturbations, which, in our case, act in concert with the following ionizing radiation, producing the interaction of two antiproliferative/destructive factors.
